IPC: H02H7/10
Filed: 1993-03-01
Abstract: PURPOSE:To enhance the safety and reliability by interrupting a DC power supply output only when the human body mistakenly touches an output line or during the occurrence of power leakage in a power supply system. CONSTITUTION:Voltage detection means 32 is installed between a converting circuit 20 and its circuit breaker 21 for input, and the normal state of the input voltage is detected by the closing of both + and - contacts of the circuit breaker 21. By this detection, a relay contact 34 between the mid-point of capacitors 22 and 23 and earth 5 is closed, and a current-carrying circuit for absorbing noise and surge is made effective. By doing this, any stray current flowing to current detection means 14 due to the time delay between both the contacts of the circuit breaker 21 can be prevented without using labor, and the current detection means 14 can interrupt a circuit breaker 13 for the output from a DC power supply 10 only when an actual ground fault or the like including the operating period of the circuit breaker 21 has occurred. Also, resistors 30 and 31 are connected in parallel to the capacitors 22 and 23 in order to prevent the stray current flowing when the values the capacitors 22 and 23 are unbalanced, thereby also preventing erroneous operation in detecting ground fault or the like.
